I'm the developer of the iPhone app Soccer Aloud.
Soccer Aloud reads web pages aloud to you.You tell it what you want to hear, it saves the pages on your device, and it reads them back to you using the voice of a classy English gent. Unlike some other text-to-speech apps, it understands the gist of what it's reading to you so it's got good fluency and pronunciation. I've also incorporated a couple of subtle, but significant techniques that really enhance the quality of the speech.
Soccer Aloud is specifically designed for football fans, but can in fact read most web pages.
It's not specifically designed for blind and low-vision users, but I think it's something that you'd be interested in, so I'm looking for beta testers who can help me make sure that it works for you.
If anyone is interested, please email me at email@example.com.
I'd be happy to answer any questions you have about the app.
